Facial Affect Differences in Autistic and Non-Autistic Adults Across Contexts and Their Relationship to...

Area of Science:

• Psychology
• Neurodevelopmental Disorders
• Social Cognition

Background:

• Autistic individuals often face negative first impressions due to stigma surrounding social behaviors.
• Facial expressivity influences general population first impressions, but its role in autism perception is understudied.
• It remains unclear how autistic facial expressivity varies with context and affects observer impressions.

Purpose of the Study:

• To investigate if differences in facial emotional expressivity in autistic adults correlate with first impressions formed by non-autistic observers.
• To examine how contextual demands (job interview vs. personal interest) influence autistic facial expressivity and subsequent perceptions.
• To assess the impact of diagnostic disclosure on how autistic individuals are perceived.

Main Methods:

• Video-recorded autistic and non-autistic adults in job interview and personal interest contexts.
• Quantified facial affect (positive, neutral, negative) using specialized software.
• Assessed first impressions and perceived success via observer ratings, correlating these with facial expressivity and context.

Main Results:

• Autistic adults exhibited less overall positive affect compared to non-autistic adults.
• Negative affect displays by autistic individuals were linked to poorer first impressions in job interviews.
• First impressions of autistic individuals improved in personal interest contexts and upon disclosure of their diagnosis.

Conclusions:

• Divergent facial emotional expressivity in autistic people contributes to less favorable impressions from non-autistic observers.
• Contextual factors and diagnostic disclosure significantly modulate perceptions of autistic individuals.
• Findings highlight potential biases in facial expression interpretation contributing to disparities faced by autistic adults.
